Based on 37% renewable ingredients, Sorona fibre earned the Oeko-Tex Standard 100 certification indicating that it has been tested to be free from harmful levels of more than 300 potentially dangerous substances.

Oeko-Tex granted Sorona a Class 1 certification signifying that it meets the most stringent limit levels Oeko-Tex requires for products intended for use by infants and toddlers age three and younger.

High performance fibre

 “The independent, voluntary Oeko-Tex certification is an important part of the complete Sorona sustainability story,” commented Renee Henze Marketing Leader, at DuPont Biomaterials.

“We created Sorona to be a high performance fibre that is better for the environment but, to be truly sustainable, Sorona also must not contain substances harmful to the consumer. The Oeko-Tex testing and certification process confirms this.”


Oeko-Tex Standard 100 certified products are tested for concerning substances such as pesticides, heavy metals like lead and mercury, formaldehyde, carcinogenic dyes, residual surfactants, and a long list of other chemicals that can have harmful effects on people as well as on the environment.

The certification requires annual renewal and Oeko-Tex conducts site visits and retail audits to help certificate holders maintain the standard’s requirements. Sorona’s Oeko-Tex certification also means that the fibre can be used in other Oeko-Tex certified textile and apparel products without concern.

“Long time certificate holders like DuPont Sorona are leaders in the textile industry’s ongoing efforts to operate more sustainably across the global supply chain,” said Ben Mead who represents OEKO-TEX in North America. “We look forward to continuing our partnership for many years to come.”
